这是我的完整代码，我用来从一个网站上的联系表单发送电子邮件。 尽管使用了所有最佳实践（Header等），结果是:
1）每次发送给用户的确认邮件都是gmail垃圾邮件，并被称为网络钓鱼
2）管理电子邮件被标记为网络钓鱼
有人能帮我吗？ 谢谢！

你需要使用标题。 这对我很有效:
$to = "mail@example.com";
$subject = "your subject";
$body = "<p>Your Body</p>";
$headers = "From: Sender Name <mail2@example.com>" . "\r\n";
$headers .= 'MIME-Version: 1.0' . "\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
mail($to, $subject, $body, $headers);
此外，您还可以在您获得域名的注册机构中为SPF添加TXT记录。 转到DNS设置并添加以下TXT记录:
类型:txt
主机:example.com
值:v=spf1 ip4:your.server.ip.here~all
ttl:automatic
这是用来验证邮件没有被欺骗的。
你不能明确地控制你的电子邮件是否被标记为垃圾邮件，但是你可以做一些事情来帮助你。
